Application filed September 24, 1924.

To @ZZ whom t may concern.'

Be it known that I, Hnnnn'r A. MARTIN, a citizen of the United States,residing at St. Louis, Missouri have invented a new and useful Devicefor Cleaning lValls and Ceilings, o'tl which the tollowing is aspecification. f

This invention is a device for cleaning walls and ceilings.

An object o'lf the invention is to provide a device for holding materialiior cleaning walls, ceilings, etc., that may be economicallymanufactured and sold and which is capable of adjustment to hold piecesof cleaning material of dil'lierent sizes and which is also providedwith means for forcing the material to and holding the material inposition in the device for proper use.

@ther objects will appear from the iollowing description, referencebeing made to the drawing in which Fig. 1 is a plan view of theinvention.

Fig. 2 is a side elevation.

F ig. 3 is an end elevation.

F ig. i is a view showing the parts of the device in detachedrelationship.

In the embodiment of the invention shown the cleaning material holder ismade in two parts, and said parts may be castings. One oi said partscomprises a plate 1 having a tapered seini-tnbular handle engaging part2 integral therewith and extending obliquely there'lroni. Said part alsohas a flange .-l integral with its upper edge and thickened portions flextending downwardly along the outer side oit the plate 1 and across theitlange 3. The handle engaging portion 2 is between the thickenedportions it.

The other part of the cleaning material holder is a casting comprising aplate 5 matching the plate 1 and having` integral with the upper edgethereoi a tapering semitubular handle engaging part 6 matching thehandle engaging part 2. The integral union between the plate 5 and thehandle engaging part G is strengthened by a flange 7 extending into arecess 8 in the flange 3.

The handle engaging parts 2 and 6 are provided with holes 9 throughwhich a bolt 10 is passed for co-operation with a screw 11 which alsopasses through said handle en gaging parts and through the end of thehandle 12 to hold the parts of the device in rigid relationship. Thebolt 1() is pret- Serz'al No. 739,498.

erably provided with a wing nut 13 which is capable of manual operationto clamp or release the parts. The body 14 of cleaning material may be olany appropriate composition and is engaged between the plates l and 5,the clamping bolt 10 and screw 11 serving to clamp the plates upon thecleaning material.

Each of the thickened portions 4i has a threaded hole therethrough. Ascrew 15 eX- tends through each of said threaded holes. The lower endsof the screws 15 have swiif'el connection 1G with a bar or plate 17between the plat-es 1 and 5. The bar or plate 1? serves as a follower tolorce the cleaning material outwardly when said material becomes worn.The upper end ot' each of the screws 15 is provided with a handleportion 18 whereby said screws may be manually turned.

The flanges 3 and 7 serve to strengthen the plates 1 and 5. Near theends of the iange 7 thickened portions'19 are formed which aiiord addedstrength and permit the plate 5 to be made relatively thin and light.

My invention is oi simple and inexpensive character and may be easilyremoved and detached. The parts may be made of relatively light weightand at the same time of' such strength that they will not break.

l/Vhat I claim and desire to secure by lLetters Patent is 1. A device ofthe character described comprising a plate, a flange integral with oneedge of said plate, a material pressing device supported by said flange,an additional plate cooperating with said first plate to form a jaw, aprojection extending 'from each of said plates, and a clamping'devicepassing through said projections and holding said plates in properrelationship.

2. A device of the character described comprising a pair of castings,each of which includes a plate and an obliquely extending semi-tubularhandle engaging portion; devices passing through said haidle engagingportions for holding a handle in connection therewith and for holdingsaid platesv in rigid spaced relationship; and means supported betweensaid plates for forcing cleaning material in a direction opposite fromsaid handle engaging portions.

Hnnnnirr A. MARTIN.
